TMK, nothing material is going to be leaving that mass. Except maybe @ the other end of any wormhole in space/time that might actually exist - the theory is still up in the air, as far as I know. Size isn't a factor, either - you can look @ any good reference for details.
Pulsars are thought to be regular ejections of plasma/radio waves from the poles of a neutron star (kinda related to a black hole) - very energetic, & dangerous if you're too close, or if you're in the path of a repeated pulse.
